WATER-CLOSET BOWL.

To all whom it may concern:

Be it known that I, HARVEY D. FARRIs, a citizen of the United States,residing at Spokane, in the county of Spokane'and State of Vashington,have invented certain new and useful Improvements in \Vater- ClosetBowls, of which the following is a specification.

This invention relates to improvements in water closet bowls andmoreparticularly to improvements in the safety overflow de* vices ofsuch a bowl, this application constituting a division of my applicationfiled April 7, 1919, Serial No. 288,179.

Various improvements have been proposed for preventing the overflow of awater closet bowl when the siphon leg thereof becomes clogged. Forexample, in one type of bowl there is provided, in the forward wall, anascending overflow leg and a descending leg, the first mentioned legopening at its lower end into the bowl at a point forwardly of andopposite the intake end of the siphon leg and close to the bottom of thebowl. In such a construction it is presumed that in the event the siphonleg becomes clogged and the water level in the bowl reaches the junctureof the ascending and descending legs of the overflow, any additionalvolume of water entering the bowl will rise through the ascending legand flow downwardly through the descending leg and, of course, thence tothe down pipe. Theoretically such a construc-' tion is practicable but Ihave found that in actual use it frequently will not operate asintended. For example, it is a well known fact that the excrementdeposited inthe bottom of the bowl is not immediately carried upwardlyinto and through the siphon leg when the! bowl is flushed but will firstbe carried back and forth several times before being caused to enter thesaid siphon leg. As the excrement is washed back and forth in the bottomof the bowl a greater or less quantity thereof is almost certain to'become lodged in the ascending leg of the overflow system, with theresult that in time this leg will become clogged without this fact,however, being -made apparent. Then, should the siphon leg becomeclogged the bowl, when flushed, will be flooded and will overflowbecause of the inability of the overflow system to take care of thesurplus water. It is, therefore, another important Specification ofLetters Patent.

object of the present invention to provide in a water closet bowl, anovel arrangement of .safety overflow legs, the arrangement being suchas to insure against clogging of the ascending leg or legs and toprovide for the proper overflow of water even in the event one oftheascending legs should become clogged. I

In the accompanying drawings:

Figure 1 is a perspective view of a water the present invention;

Fig. '2 is a horizontal sectional view therethrough taken in a planeabove the upper ends of the ascending and descending legs of theoverflow system;

Fig. 3 is a vertical front to rear sectiona view through the bowl.

In the drawings the numeral 1 indicates In general a water closet bowlhaving the usual flushing channel 2 surrounding its upper margin andprovided near its top at 1ts rear side with the usual outlet flushingspout 3 through which water is to be discharged in a downward directionto flow over the bottom of the interior of the bowl so as to carry offthe excrement through the upwardly and forwardly inclined siphon leg 4,the excrement passing through the down passage 5 and out through thedischarge 85 opening 6 with which is connected the down pipe (notshown).

I will now describe in detail the means provided for preventing floodingand overflow of the bowl. As clearly illustrated in 90 Figs. 1, 2 and 3of the drawings, the bowl located below the supply passage for the 100flushing spout 3. At each side of the descending overflow leg 27, thebowl is formed in its rear. wall with an ascending overflow leg 29, andthese legs 29 extend downwardly" and in a general forward directionabout the 105 sides of the bowl at the rear thereof and communicate attheir lower ends by way of the openings 30 with the interior of thebowlnear the bottom thereof. At their upper ends, these legs communicatewith the 110 closet bowl constructed in accordance with overflow intothe descending leg 27 and will pass downwardly through said leg and-outthrough the discharge passage 6. Referring particularly to Fig. 2 of thedrawings, it Will be observed that the openings 30 are located atopposite sides of the bottom of the interior of the bowl andconsequently at opposite sides of the intake or lower end of the-siphonleg 4. As a consequence, even though the deposited excrement be washedback and forth over the bottom of the bowl before beingcarried upwardlythrough the siphon leg 4, none will move over the openings 30 andconsequently there is little likelihood of the deposited excremententering the ascending overflow legs 29. Should the siphon leg 4 becomeclogged, water will, of course, flow upwardly through the legs '29 into.the chamber 28 and thence downwardly through the leg 27 and out throughthe pipe 6, so as to prevent flooding of the bowl, and this will takeplace even though one of the legs 29 should become clogged, although dueto the disposition of the openings 30, this is extremely unlikely tooccur.

Having thus described the invention, what is claimed as new is:

1. A water closet bowl having an outlet, a descending overflow leg incommunication with the outlet, and an ascending overflow leg incommunication with the upper end of the descending leg and communicatingwith the interior of the bowl through the bottom thereof at one sideofthe front to rear middle line of said bottom.

2. A water closet bowl having an outlet, a descending overflow legcommunicating with the outlet, the bowl having a chamber incommunication with the upper end of the said descending leg, and anascending overfiowleg at each side of the descending leg, the ascendinglegs communicating at their upper ends with the said chamber and at.their lower ends with the interior of the bowl through the bottomthereof at opposite sides of the front to rear center line of the saidbowl.

3. A water closet bowl having a siphon discharge leg inclined upwardlyand forwardly from its bottom and having a discharge branch extendingdownwardly to the outlet from the bowl, the bowl having a water inlet atthe rear side of its interior arranged to discharge water downwardly andforwardly in the direction of the intake end of the said siphon leg, adescending overflow leg in communication with the out- HARVEY n.FAR-BIS.
